pids - list calling shell process ids

When invoked as a shell builtin, pids lists one or more of the calling process ids determined by getpid(2), getppid(2), getpgrp(2), tcgetpgrp(2) and getsid(2). Unknown or invalid ids have the value -1.

-f, --format=format

List the ids specified by format. format follows printf(3) conventions, except that sfio(3) inline ids are used instead of arguments: %[-+][width[.precis [.base]]](id)char. The supported ids are:

pid

The process id.

pgid

The process group id.

ppid

The parent process id.

tid|tty

The controlling terminal id.

sid

The session id.

The default value is PID=%(pid)d PPID=%(ppid)d PGID=%(pgid)d TID=%(tid)d SID=%(sid)d.

getpid(2), getppid(2), getpgrp(2), tcgetpgrp(2), getsid(2)
